The economy of SR1 initially bothered me because every planet added its surplus toward a magical bank, where my resources could persist outside of time and space (regardless of distance and storage impossibilities). But I got used to it. It was the same as almost every other RTS's magical bag of holding. I learned to enjoy pulling a billion resources in less than a minute, when the need arose. Will this feature be continued in SR2 or will resources exist only in local storage, shared between trade lanes? Maybe the universal bank could be toggled at the start of a game, to appease both sensibilities.
I also hold reservations about the depiction of resources themselves. How many square feet of farmland is required to feed a person? Let's hypothetically say 100 sqft. is enough. How many of those gardens can be built over a 100sqft. area? Is it not obviously one? Technology between 1975 and 1985 allowed for 110, vertical stories. With modern technology the answer is 163 vertical stories, and really no limits in the future. Hydro/Aero-ponic technology coupled with climate and light control and automated labor could realistically compete with traditional farming industries. Imagine just one city block sized skyscraper converted into a hydroponics farm and how many people it could continuously feed. Please don't say that my Paldinians with space-faring technology are incapable of feeding multiple planets of equivalent population, simultaneously. There is a finite supply of uranium, sure; but not foodstuffs. Industrial capacity to produce firearms and munitions, sure; but not fruits and vegetables.
I'm worried how difficult it will be to balance the trade routes, and how time consuming it will be to set them up even with the blindest inefficiency. But that seems like an obvious problem, so I have full faith that you guys will make sure they do not interfere with actually playing the game.
